When are the pilot lights illuminated?

The pilot lights are designed to indicate the operational status of equipment and are illuminated when the buck and head contactors are energized. This means that when the system is actively functioning and the contactors, which are critical components for controlling electrical power, are closed, the pilot lights will be lit. Their illumination serves as a visual cue, informing operators that the device is on and operating properly. This information is crucial for safe operation and maintenance of equipment, as it helps personnel quickly determine the readiness of the system at a glance.
